Modular Rifle Chassis System
There is no definitive term used by the shooting industry for these bolt action rifle chassis. In my personal opinion Rifle Chassis System best describes these Aftermarket Rifle Stocks. Here a Modular Rifle I added the term “Modular” as most of these Rifle Chassis are modular in construction and often customizable in ways not possible with Traditional Rifle Stocks. Traditional stocks whether sniper, tactical or competitive are often adjustable to fit a shooter. The Modular Rifle Chassis System would be better explained as “Adaptable”. The chassis are not only adjustable like their traditional counterparts. The Rifle Chassis Systems are adaptable or configurable to the shooter and the task. Typically there are many buttstock options such as proprietary adjustable and and folding to the ability to accept AR-15 stocks. Some chassis offer different forearms, forearm side panels, pistol grips and side panels.

The MDT Adjustable Core Competition Chassis System is designed primarily for Precision Rifle Series and National Rifle League shooting disciplines.
Magpul has followed up their Pro 700 Chassis Remington 700 Short Action Chassis with the new Pro 700L series. The Pro 700L is the long action version of the chassis for popular calibers such as .300 Winchester Magnum, 30-06 Springfield, 7mm Remington Magnum etc. The chassis are feature rich and available in 3 colors. They are priced between $900-$1000 which is higher than I would expect given how competitive the field is. I plan on getting one and seeing how it compares to my MDT’s.
MDT has just re-launched the Light Sniper System (LSS) chassis with second generation design and feature updates. The LSS GEN2 is designed for use with compact, short barrelled rifles to provide light-weight, accuracy improvement and consistency.
MDT has introduced a new chassis and brand with the release of the ORYX. The ORYX is a one-piece integrated aluminum chassis and buttstock created to improve the consistency and accuracy of a bolt action rifle that retails for under four hundred dollars.
The MDT ACC: A competition chassis designed to give shooters complete control over balance and recoil reduction – with a little help from solid steel.
The Adjustable Core Competition Chassis has a fully customizable steel weight system integrated in the buttstock, barrel channel and forend. Balance your rifle, reduce recoil, stay on target – with the ACC (and 9 pounds of modular weight) you can have your metal as heavy as you like it.
The ACC (Adjustable Core Competition) Chassis is designed around an integrated, modular weight system which allows you to customize the balance and mass of your rifle to maximize performance and minimize recoil.
The ACC comes with a Skelton Rifle Stock with a steel butt pad plate for added weight and has a dedicated space to add even more weight to the stock if required.
The ACC Chassis features a full Arca rail the entire length of the forend and M-LOK mounting points for accessories and additional forend weights – both internal and external – allowing you to add up to an additional 9 pounds of steel to your rifle.
The Modular Driven Technologies LSS-22 Chassis System for .22LR caliber rifles is lightweight and compact, and adopts the same footprint as the centerfire MDT LSS Chassis. You will notice a significant improvement in accuracy due to the V-shaped bedding and free floated fore-end, which allows for barrel contours up to 1″ in diameter.
When Magpul announced the Remington 700 Hunter Stock I remember thinking to myself that it wouldn’t be long until we see a precision rifle chassis from them. I also remember thinking that a well designed priced right precision rifle chassis from Magpul could dominate the low to mid range rifle chassis market. Well I’m here to report the good news that Magpul has officially announced the “Magpul Pro 700” rifle chassis. Unfortunately though I’m more than a little surprised by the $1000 MSRP. That is three times the cost of the hunter stock and in my opinion about 1/3 higher than it should be because at that price shooters are at the price of a complete Savage Stealth or Ruger Precision Rifle. Those are great tack driver chassis based rifles for the cost of the Magpul Pro 700 chassis. Insult to injury the lack of an ARCA plate is a deal breaker for precision rifle crowd. Now with that said I’m a big believer in actually trying hardware first hand instead of relying on critical negative reviews of a product very few have seen or touched. Additionally Magpul still has time to address any perceived shortcomings pointed out by the community.

I always find it interesting what the predominant questions are that come from the contact page at a website. in the case of this website Modular Rifle I think all of the questions except for one have one way or another pertained to The Remington RACS Chassis and variants used on the Remington Military Sniper Rifle XM2010 (now known as the Remington M2010) and it’s siblings, Remington MSR, Remington PSR and the Remington CSR. There’s quite a bit of confusion and it’s completely understandable. Maybe we can sort some of it out.

The MDT TAC21™ chassis system a combination of benchrest accuracy, superior ergonomics and specialized design. This chassis brings the bolt action rifles to the next level in versatility and modularity, with an instant improvement in accuracy.
The chassis system is manufactured out of billet 6061-T6 aluminum, which has been hard anodized to mil spec type III for extra strenth, and has been finished with Cerakote™ in Black or Flat Dark Earth (FDE).
TAC21™ chassis is engineered to minimize warping and distortion. The rifle receiver only makes contact with the TAC21™ chassis on the V shape bedding and recoil lug area insuring the best accuracy and repeatability. The generous clearance on the fore-end makes any barrel (diameter up to the receiver size – 1.350”), free floating.
Inherently the TAC21™ has a straightline design, meaning that the recoil comes straight back instead of making the front of the rifle kick upwards. This results in more accurate and quicker follow up shots. This also translates to a decrease in felt recoil and comfort.
